The best football teams from across the Americas

Sixteen teams from across the Americas have gathered in the United States for this special one-off edition of the Copa América, which is being staged to mark the tournament's 100th anniversary.

Messi, Suárez, James among the stars

Argentina's Lionel Messi, Uruguay's Luis Suarez and Colombia's James Rodriguez are among the stars due to be in action throughout the tournament, which runs from June 3 to 26.

Excitement at the event appears to now be running high, despite a troubled build-up dogged by corruption allegations that threatened to derail the event.

Biggest tournament in the USA since the 1994 World Cup

Ten teams from South America are joined by six teams from the North America, Central America and Caribbean region (CONCACAF), in what is arguably the biggest tournament to be staged on US soil since the 1994 World Cup.

The tournament is being seen in some quarters as a statement of intent for a bid for the 2026 World Cup, which US officials have signaled they intend to bid for as football in the United States steadily grows in popularity.

Levi's Stadium in Santa Clara

The gleaming Levi's Stadium in Santa Clara -- home of the San Francisco 49ers and the venue for this year's Super Bowl -- is expected to be close to its 68,500 capacity on Friday for the USA's Group A opener against Colombia.

Whether spectator demand for other matches will be as high is doubtful; few are expecting matches involving the tournament minnows to be sell-outs.

In comments to Sports Illustrated, United States Soccer Federation chief Sunil Gulati said he expected the tournament to meet its targets.

"It's a big event, and I think our goals will be met by the time the event is over in terms of attendance and interest," Gulati said.

"There's a lot of star power, and we open with a great game with the US and Colombia."

Most teams have full-strength squads

Most teams have chosen full-strength squads, although injuries and the proximity of the Olympics have deprived Brazil of several first choice players including Barcelona superstar Neymar.

"Everyone has brought the best players who are available to them and they're taking it seriously. That's a plus," said Gulati.

Copa América: a logistical triumph

That the tournament is taking place at all is something of a logistical triumph.

Although first announced in 2014, the fate of the event hung in the balance for much of 2015 after the arrest and indictment of several of the officials from South America and CONCACAF responsible for dreaming up the tournament.

When plans for the tournament were launched at a glitzy event in Miami two years ago, CONCACAF President Jeffrey Webb stood proudly alongside South American federation (CONMEBOL) chief Eugenio Figueredo.

But Webb and Figueredo were among several officials arrested in Switzerland in May last year as part of the US-led corruption investigation that ultimately led to the sensational downfall of FIFA President Sepp Blatter.

With impeccable timing, Webb is due to appear in a New York courtroom on Friday -- the day of the tournament's opening match -- to face sentencing for his role in the scandal.

Figueredo, 84, was extradited to Uruguay from Switzerland last December and also faces criminal prosecution.

Both Figueredo and Webb -- as well as former CONMEBOL chief Nicolas Leoz -- are accused of pocketing millions of dollars in bribes linked to the award of media rights for the tournament, part of a scam dubbed a "World Cup of Fraud" by US prosecutors.

Organizers will hope that the sleazy background will be forgotten once the action finally gets under way.
